| <div class="markdown level0 summary"><p>Grid cache transaction. |
| <p> |
| Cache transactions support the following isolation levels: |
| <ul><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_ReadCommitted">ReadCommitted</a> isolation level |
| means that always a committed value will be provided for read operations. With this isolation |
| level values are always read from cache global memory or persistent store every time a value |
| is accessed. In other words, if the same key is accessed more than once within the same transaction, |
| it may have different value every time since global cache memory may be updated concurrently by |
| other threads.</li><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_RepeatableRead">RepeatableRead</a> isolation level |
| means that if a value was read once within transaction, then all consecutive reads will provide |
| the same in-transaction value. With this isolation level accessed values are stored within |
| in-transaction memory, so consecutive access to the same key within the same transaction will always |
| return the value that was previously read or updated within this transaction. If concurrency is |
| <a class="xref" href="Apache.Ignite.Core.Transactions.TransactionConcurrency.html#Apache_Ignite_Core_Transactions_TransactionConcurrency_Pessimistic">Pessimistic</a>, then a lock on the key will be |
| acquired prior to accessing the value.</li><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_Serializable">Serializable</a> isolation level means |
| that all transactions occur in a completely isolated fashion, as if all transactions in the system |
| had executed serially, one after the other. Read access with this level happens the same way as with |
| <a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_RepeatableRead">RepeatableRead</a> level. However, in |
| <a class="xref" href="Apache.Ignite.Core.Transactions.TransactionConcurrency.html#Apache_Ignite_Core_Transactions_TransactionConcurrency_Optimistic">Optimistic</a> mode, if some transactions cannot be |
| serially isolated from each other, then one winner will be picked and the other transactions in |
| conflict will result in <code>TransactionOptimisticException</code> being thrown on Java side.</li></ul> |
| Cache transactions support the following concurrency models: |
| <ul><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionConcurrency.html#Apache_Ignite_Core_Transactions_TransactionConcurrency_Optimistic">Optimistic</a> - in this mode all cache |
| operations |
| are not distributed to other nodes until <a class="xref" href="Apache.Ignite.Core.Transactions.ITransaction.html#Apache_Ignite_Core_Transactions_ITransaction_Commit">Commit()</a>. |
| In this mode one <code>PREPARE</code> message will |
| be sent to participating cache nodes to start acquiring per-transaction locks, and once all nodes |
| reply <code>OK</code> (i.e. <code>Phase 1</code> completes successfully), a one-way <code>COMMIT</code> message is sent |
| without waiting for reply. If it is necessary to know whenever remote nodes have committed as well, |
| synchronous commit or synchronous rollback should be enabled via |
| <code>CacheConfiguration.setWriteSynchronizationMode</code>. |
| <p> |
| Note that in this mode, optimistic failures are only possible in conjunction with |
| <a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_Serializable">Serializable</a> isolation level. In all other cases, |
| optimistic transactions will never fail optimistically and will always be identically ordered on all |
| participating Ignite nodes.</li><li><a class="xref" href="Apache.Ignite.Core.Transactions.TransactionConcurrency.html#Apache_Ignite_Core_Transactions_TransactionConcurrency_Pessimistic">Pessimistic</a> - in this mode a lock is |
| acquired on all cache operations with exception of read operations in |
| <a class="xref" href="Apache.Ignite.Core.Transactions.TransactionIsolation.html#Apache_Ignite_Core_Transactions_TransactionIsolation_ReadCommitted">ReadCommitted</a> mode. All optional filters passed |
| into cache operations will be evaluated after successful lock acquisition. Whenever |
| <a class="xref" href="Apache.Ignite.Core.Transactions.ITransaction.html#Apache_Ignite_Core_Transactions_ITransaction_Commit">Commit()</a> is called, a single one-way <code>COMMIT</code> |
| message is sent to participating cache nodes without waiting for reply. Note that there is no reason |
| for distributed <code>PREPARE</code> step, as all locks have been already acquired. Just like with |
| optimistic mode, it is possible to configure synchronous commit or rollback and wait till |
| transaction commits on all participating remote nodes.</li></ul> |
| <p> |
| In addition to standard <code>CacheAtomicityMode.TRANSACTIONAL</code> behavior, Ignite also supports |
| a lighter <code>CacheAtomicityMode.ATOMIC</code> mode as well. In this mode distributed transactions |
| and distributed locking are not supported. Disabling transactions and locking allows to achieve much higher |
| performance and throughput ratios. It is recommended that <code>CacheAtomicityMode.TRANSACTIONAL</code> mode |
| is used whenever full <code>ACID</code>-compliant transactions are not needed. |
| <example> |
| You can use cache transactions as follows:<p> |
| <pre><code>ICacheTx tx = cache.TxStart(); |
| |
| try |
| { |
| int v1 = cache<string, int>.Get("k1"); |
| |
| // Check if v1 satisfies some condition before doing a put. |
| if (v1 > 0) |
| cache.Put<string, int>("k1", 2); |
| |
| cache.Removex("k2); |
| |
| // Commit the transaction. |
| tx.Commit(); |
| } |
| finally |
| { |
| tx.Dispose(); |
| }</code></pre> |
| <p></example></p> |
